corporation of Virginia Filed .lune 6, 1958, Ser. No. 740,469 36 Claims. (Cl. 112-104) This invention relates to new and useful improvements in the art of bag making, and in particular concerns itself with the making of bags having a tag or label stitched at one edge thereto. Bags of this general type are widely used for retaining coresV or samples taken in the Well drilling industry and for this reason are frequently referred to in the art as core bags.

One type of a machine for making bags of this general nature is disclosed in my Patent No. 2,313,433, issued March 9, 1943, wherein a continuously moving web of material is doubled longitudinally upon itself to form the side walls and bottom of bags with an open mouth and wherein tags are inserted at predetermined intervals between the folds f the continuously moving web, whereupon the web is cut into individual bags each having a tag therein disposed so that when the cut edges are subsequently stitched, the tag is secured by one edge tothe bag. As already noted, in the machine according to my prior patent the tags are inserted into the folded or doubled web, while the same is continuously moving, and the arrangement is such that the tag is afxed to the bottom edge of the finished bag. n i

The principal object of the present inveution'is to provide an improved and modified arrangement whereby the tag may be aflixed to one side edge rather than to the bottomedge of successive bag members and whereby the tag inserting operation yis performed after the moving web is cut into individual bag members which are held relatively stationary at the cutting position while the tag is being inserted. As a result, the arrangement ofthe machine is not only simplified, but much greater accuracy is attained in proper positioning and securing of the tag in relation to the finished bag.

An important-feature of the present invention involves i the provision of improved means for separating the cut side edges of the bag to facilitate the insertion of the tag therebetween, such means utilizing a pair of'coacting suction units one of which holds one side edge of the bag relatively stationary while the other moves the superposed side edge away from the relatively stationary edge during insertion of the'tag.

Another important feature ofthe present invention involves the provision of means for feeding tags in a continuous strip form to the bags, the strip of tags being easier to handle, feed Vand `otherwise manipulate than individual tags which often adhere together or miss being picked up by the feeding means.

In conjunction with the last mentioned feature, another important feature of the present invention resides in the lprovision of means including a photo-electric cell which scans the strip of tags and is adapted to detect markings located at spaced points thereon, vfor controlling the feeding of the tag strip in an intermittent manner, coordinated with the production of individual bags from the web.

As in the machine according to my prior Patent No. 2,313,433, the bags completed by the present invention have the tag at the inside thereof but are inside out. As such, they are subsequently delivered to a Stringing machine of a conventional type which not only inserts a string into a hem at the mouth of the bags, but also reverses the bags from the inside out so that the tag is ultimately at the outside of the finished bag.

With the above more important objects and features carrier raised;

The accompanying FIGURE 1 illustrates a finished bag after the same has been processed by a conventional Stringing machine, such as -that shown in my Reissue Patent No. 23,196, which inserts a string A11 into hems 12 at the mouth of the bag and reverses the bag inside out so that the tag or label -13 is at the outside of the bag. The closed bottom of the bag is indicated at 14 and the opposite side edges 1S of the bag have been secured together by lines of stitching 16. The t-ag 13 is secured by one of its edges between the side edges 15 at one side of the bag, through the medium of the line of stitching 16 passing through the side edges of the bag between which the tag is inserted.

The machine in accordance with this invention completes the bag to the point where it is inside out and the tag 16 is at the inside thereof, so that it is ready for delivery to the Stringing machine above mentioned. The bag making material in the machine according to the invention is in the form of a continuous web 10a, unwound from a suitable roll 10b and doubled longitudinally upon itself as indicated at r10c in FIGURE 2, whereupon it is intermittently fed between a pair of rollers -17 to what may be called a primary work station 18. At this station successive portions of the doubled web of a size suicient to form a bag are successively clamped against the table top 23 and individual bag members cut from the successively clamped web portions, and while still at the primary station one side of each successive bag member is opened and a tag inserted between the bag layers of the doubled web. The tag members are formed from a continuous strip of tag forming material, which strip is intermittently advanced in timed relation to the web advancing, bag cutting and bag opening mechanisms, as will be more fully described hereinafter. Prior to the longitudinal doubling of the web 10a, suitable sewing machines (-not shown) are employed for sewing the hems 12 at both longitudinal edges of the web, all this being substantially in accordance with the teachings of my prior Patent No. 2,313,433, already mentioned or of my Patent No. 2,667,132.

It will be noted, however, that whereas in my prior Patent No. 2,313,433 the tags or labels are inserted between two layers of a continuously moving doubled web,

in accordance with the present invention the tags or labels are inserted into the sides of successive bag members which have already been cut yfrom the web, each of which bag members is firmly clamped in stationary position, while successive tags are inserted into the successive clamped bag members at the primary station. This makes possible the accurate positioning of the tag or label with reference to the bag, which was impossible in accordance with my prior patent wherein the tag or label was inserted between the folds of a moving web. Moreover, while in accordance with my prior Patent No. 2,313,433 a special sewing machine is required to sew the tags into the closed bottom of the folded web material, the necessity for such special machine is eliminated in accordance with the present invention, and instead of such machine one of the usual sewing machines employed for sewing together the sides of the individual bag members also serves to secure the tags or labels into successive bag members. In this manner not only is a more accurate and convenient arrangement of the tags or labels within the bag insured, but an entire sewing machine is eliminated, resulting in a marked saving in the cost of the apparatus as a whole, and in addition the individual bags resulting from the use of my improved method and apparatus are more satisfactory to the industry than were the bags produced i-n accordance with the method land apparatus o-f my prior Patent No.V

Knife means are provided for severing the web along a line 19 at one side of the primary station 18, while temporarily clamped at said station so as to result in the formation of a series of partly completed, individual bag members y10 each of which has superposed but free or unsecured side edges 15 at the opposite sides thereof.

The tags or labels 13 are fed from a suitable roll in the form of a continuous strip 13a to the primary station 18, at which point means are provided for opening or separating vthe free side edges at one side of the clamped bag and permitting insertion of the leading tag in the strip into the bag so that an edge of the inserted tag is disposed between the separated edges of the bag. The leading tag is then severed from its strip and the individual bag with the inserted tag is then delivered by mechanical means to what may be called a secondary work st-ation 20 having a pair of sewing machines 21 located thereon so as to secure the free side edges 1S of the bag together by the lines of stitching 16, and simultaneously secure the tag 13 in place between the side edges at one side of the bag. The lines of stitching 16 continue uninterrupted from bag to bag, so that the bags emerge in a chain fashion in readiness for delivery to the Stringing machine.

Referring now to the accompanying drawings in detail, the machine in accordance with the invention comprises a suitable framework 22 supporting a stationary bag supporting top plate member 23 on which the primary and secondary work stations 18, 20 are located in adjacent relationship, longitudinally of the bag being formed. The rollers 17 through which the doubled web 10c is intermittently fed to the station 18 are located at one side of the primary station 41S, being mounted on a pair of shafts 24 which are simultaneously rotated by intermeshing gears 25, as is best shown in FIGURE 4.V The lower of the shafts 24 carries a conventional over-running clutch 26 having a pinion 27 aflixed thereto, the pinion, in turn, meshing with a toothed segment 28 which is pivoted at 29 to the frame 22. A link 30 extends from the segment 28 to a cam shaft 31 journalled in the frame 22 and has a yoke portion 30a which slidably straddles the camshaft as shown in FIGURE 4. The yoke portion 30a carries a follower 30-b which operatively engages a suitable groove (not shown) in the side of a cam 32 secured to the shaft 31. A suitable reduction gear box 33 is provided for driving the camshaft 31 as shown in FIGURE 16, the box 33 having a drive pulley 34 driven by an endless belt, or the like, from -a suitable electric motor (also not show-n). It will be apparent from the foregoing that when the cam shaft 31 is rotated, the rod 30 will impart an oscillatory movement to the segment 28 which, in tur-n, will drive the rollers 17 intermittently and unidirectionally through the clutch 26 so as to feed the web 10c, step-bystep, to the primary station 18. During each step of its feeding movement, the web is advanced to the station 18 by a distance equivalent to the width of one bag to be fabricated. At the primary stationV 18 the web portion is temporarily gripped or clamped to the stationary top plate 23 and successive individual bag portions are cut from the main body of the web, suc-cessive tags or labels are inserted laterally between the two layers of each successive bag member, prior to stitching the sides of such bag members, and at the same time sewing the labels in place within the bags.

As shown, means yare provided on the top 23 beyond the rollers 17 for severing individual bags 10 from the web 10c, these means comprising a rotary knife or cutter 35 supported by a carrier 36 which is slidable on an elongated guide 37, as shown 4in FIGURES 3, 5 and 6. The cutter 35 traverses the web 18o along the line 19 shown in FIGURE 2, the guide 37 being parallel to this line. The guide 37 is pivoted at one end thereof as shown at 38 to an upstanding bracket 39 on the top 23 and is adapted for raising and lowering movement relative to the top 23 by means of a link 40 which is pivoted at 41 to the other end of the guide and extends downwardly therefrom, :as show-n. A suitable bracket 42 extends upwardly from the frame 22 and has a forked upper end portion 42a which receives the guide 37 therein, whereby to prevent latenal deflection of the guide. When the guide 37 is lowered by the link 40, the cutter 35 is brought .against the top 23 to sever the web 10c along the line 19 while the carrier 36 slides along the guide in the direction of the arrow 43. Suitable rollers 44 are provided on the carrier 36 to engage the underside of the guide 37 and reduce friction resulting from an upward thrust on the guide when the cutter 35 is pressed against the top 23. When the carrier 36 slides along the guide in a direction opposite to the arrow 43, the guide is raised by the link 40 las indicated by the dotted lines 37a, so that the cutter 35 is ineffective.

Means are provided for clamping the web 16C against the top 23 at the station 18 to prevent the web from shifting while the cutter 35 is in operation. These means `comprise a clamping bar 45 which is pivoted at the ends thereof to connecting members 46 which, in turn, are pivoted to the end portions of the guide 37, one end of the bar 45 :also being pivotally connected by a link 47 to the base portion of the bracket 39. When the guide 37 is raised, the bar 45 is raised therewith as shown at 45a, but when the guide is lowered and the cutter is in operation, the bar 45 firmly clamps the web against the top 23. t

Y The lower end of the 4t) which raises and lowers the guide 37 is pivoted at -48 to one end of alever 49 which -is pivoted Iat 50 to a bnacket 5l.v on the frame 22, as shown in FIGURE 4. The free end of the lever 49 lis provided with a follower 52 engaging a groove 53 in the cam 32. The cam 32 actuates the 30 and the lever l,49 in a coordinated manner so that when the guide 37 is raised, the rollers 17 feed the web 10c past the raised cutter 35 to the primary station 18 while the carrier 36 slides on ,the guide from the position shown by full lines toV that shown by the dotted lines 36a. When the guide is lowered, however, the feeding of the web by the rollers 17 is interrupted by the clutch 26 and the web ris severed along the line 19 by the cutter travelling in the direction of the arrow 43.

Reciprocation of the carrier 36 on the guide 37 is effected by a link 54 which is pivoted at one end thereof to the carrier and, as shown in FIGURE 18, has its other end pivoted to a curved arm 55. The latter is pivoted at 56 to 'a bracket 57 on the frame 22 and is pivotally connected by a 58 to a cam lever 59 which is pivotally mounted at one end thereof on a shaft 61 mounted in the frame 22 adjacent and parallel to the camshaft 31. The lever 59 carries a follower 62 which engages a groove in another cam 63 secured to the shaft 31. (See FIGURE 16.)

It will be observed from the foregoing that just before and immediately after an individual, party completed bag member lil has been severed from the web lilo by the cutter 35, it lies stationary on the primary station 18 in readiness for application of the tag 13 thereto. As is best shown in FIGURES 2, 3 and 20, the tags 13 are supplied 4in the form of ia continuous strip 13a from 4a suitable roll 13b carried on a shaft 64 in the frame Z2, the strip 13a passing over a roller 65 on a shaft 66 journalled in side members 22a of the frame. The roller 65 is preferably flanged and freely rotatable. After passing over the roller 65, the strip 13a travels toward the primary station 18 along the top 23 between a pair of spaced parallel gui-de rails 67 which are suitablyraliixed toI the top 23. The strip 13a is fed intermittently to the station 18 by means hereinafter to be described, and it may be noted that the strip is provided at longitudinally spaced points thereon with markings 65 which are located at the division lines between the adjacent tags inthe strip and are subject to detection by a photo-electric cell 69 which controls the intermittent feeding movement of the strip, fas will be hereinafter explained. The cell 69 is mounted by means of |a suitable bracket 70 on the top 23 so as to scan the tag strip 13a passing between the guide rails 67 and detect the markings 63 thereon.

With reference now to the accompanying FIGURE 3 and 8-13, means are provided for separating the free, superposed `edges 15 yat one side of the individual bag 10 to facilitate insertion of the tag 13 between such side lwith a suction line or hose 75. When a bag l) is resting on the stationary top plate member 23 at the primary station 18, the free side edge portion of the lower or underlying wall of the bag covers the apertures 73 so that when air is exhausted from the chamber 71 through the hose 75, the free side edge portion of the lower wall of the bag is firmly held against the top 23 by atmospheric pressure.

The upper suction head or unit 72 is in the form of an elongated member or bar having an elogniated chamber 72a therein, from which air may be exhausted through the medium of a suction line or hose 76, connected to y a nipple 77 :at one side of the head. A plurality of suction cups 78 are mounted in a recess79 at the underside of one end portion of the head '72 and the interior of these suction cups communicates with the chamber 72 through suitable openings 8i), as will be clearly apparent.

The head or unit 72 is provided intermediate the ends thereof with an upstanding bracket 81 which is pivoted at 82 to a similar bracket S3 secured to the top 23, whereby the unit 72 is adapted for rocking movement relative to the top 23 so as to raise or lowerthe suction cups 78 relative to the top. It will be apparent from the foregoing that when the air in the chamber 72a is exhausted through the line 76, the free side edge portion Vof the upper or overlying wall of the bag 10 will adhere be raised and separated 'from the lower or underlying wall which is held relatively stationary onthe top 23 by the lower suction head'l. This resultant separation of the free edge portions ofthe walls at one side ofthe bag facilitates the insertion of the leading tag in the tag strip 13a therebetween.

The suction head 72 is raised and lowered about its pivot 82 by a rod 85 which is pivoted at 86 to the free end of a reversely curved bar 87, the latter being welded or otherwise secured to the top of the head 72' and projecting longitudinally as lwell as laterally therefrom. The rod 35' passes downwardly ythrough the top 23 and, as is best shown in FIGURE 17, is pivoted to a bell crank 88 which, in turn, is pivoted at 39 to a suitable bracket 90 at the underside of the top 23. The other arm of the bell crank 88 is pivotally connected to a link 91 extending to a cam lever 92 pivotally mounted on a shaft 93 which is adjacent and parallel to the shafts 31 and 61 inthe frame 22. The lever 92 is equipped with a follower (not shown) engaging a suitable groove 94 in a cam 95 aflixed to the camshaft 31. The shaft 93 is mounted in suitable brackets 96 on the frame 22.

A'cutter blade or knife 97,is secured by suitable screws I v98 Vto the suction head 72 for raising and lowering movement therewith, this blade being disposed transversely of ythe path of travel of the tag strip 13a between the guide after insertion of the tag, as best shown in FIGURES 8 to 13. These clamp means involve the provision of a rocker arm 99 which is pivoted at 100` to the aforementioned bracket 83 and is equipped at its lower end with a clamp member 101, pivotally attached to the rocker arm at 102. The member 101 is angulated in a horizontal plane to extend laterally under the suction head '72 as shown in FIGURE 9, into an operative engagement with the upper or overlying lwall of a bag on the station 18. The clamp member 101 is sustained in substantial parallel relation with the top 23 by a leaf spring 103 which engages the member 101 and is secured to the rocker arm 99 as Shown in FIGURE 8.

The rocker arm 99 together with the clamp member 101 is movable between a lowered or clamping position shown in FIGURES l and ll, and a raised or released position shown in FIGURE l2, regardless of the raising and lowering movement of the suction head 72, so that the member 101 may clamp the bag on the station 18 even when the suction head 72 is raised, as illustrated in FIGURE 13. The rocker arm 99 is actuated by a link or rod 104 which is pivoted to a lever 105 welded or otherwise secured to the arm 99. The link 104- passes downwardly through the top 23 and is pivoted to a cam lever 106 which, in turn, is pivoted at 107 to the aforementioned bracket 51 and is equipped with a follower 108 in engagement with the periphery of the cam 32.

To prevent any lateral shifting or deflection of the suction head 72 andthe associated knife 97, the suction head is biased laterally against a stop 109 on the top 23 by a tension spring 110 which extends from the pivot 86 to a suitable anchoring screw 111 on one of the guide rails 67.

The aforementioned lines or hoses 75, 76 for exhausting air from the chambers of the suction heads 71, 72 are connected to a T coupling 112 disposed at the top of a tubular housing 113 of a valve assembly 114 which is secured to the frame 22 by a suitable bracket 115. The underside of the housing 113 is provided with a nipple 116 which is in diametrical alignment with the T 112 and communicates through the medium of a suitable hose 117 with a motor-driven vacuum pump (not shown). A pist-on 118 is reciprocable in the housing 113 and is provided with a diametrically extending valve port or bore 119 which is registerable with the T 112 and nipple 116 when the piston is slid inwardly in the housing by an actuating rod 120, in the direction of the arrow 121 in FIGURE 23. In the inwardly slid position of the piston, the port 119 establishes communication between the vacuum pump and the suction heads 71, 72, but when the piston 118 is slid outwardly to the position shown in FIGURE 23, both the T 112 and the nipple 116 communicate with the atmosphere through the adjacent open end ofthe housing 113 so that the suction heads are de-energized while air from the atmosphere is drawn into the vacuum pump.

The valve actuating rod 120 is pivoted to a cam lever 122 on the aforementioned shaft 93, the lever 122 having a suitable follower (not shown) engaging a cam track or groove (also not shown) in a cam 123 on the camshaft 31, as indicated in FIGURE 16.

Feeding of the tag strip 13a to the primary station 18 is effected in an intermittent manner by means including a feed roller 124 secured to a shaft 125 journalled in the frame members 22a. The roller 124 is preferably rubbertired for proper frictional engagement with the underside of the tag strip 13a, it being noted that for this purpose the upper portion of the roller 124 is disposed in a recess or opening 126 in the top 23, as illustrated in FIG- URE 17. The roller 124 is actuated by an oscillatory crank arm 127 aixed tol the shaft 125 and connected by a rod or link 128` to a cam lever 129 on the shaft 93, as shown in FIGURE 16. The lever 129 carries a suitable follower engaging a cam track in a cam 130 on the shaft 31. A freely rotatable coacting roller 131 is rotatably mounted in a yoke 132 supported on a shaft 133 which is mounted above the top 23 in suitable bearings 134, the shaft 133 also carrying a rocker arm or crank 135 whereby it may be partially rotated to raise and lower the yoke 132 so that the roller 131 either presses the tag strip 13a against the feed roller 124, or, in the raised position of the yoke, leaves the tag strip relatively free so that no feeding movement is imparted thereto by the feed roller. The yoke 132 is raised through the medium of the shaft 133 by a link 136 pivoted to the arm 135, the link 136., in turn, constituting or being connected -to a reciprocable armature of a solenoid 137 affixed to the frame member 22a, as shown in FIGURE 24. However, the yoke 132 is biased to its lowered position wherein the roller 131 presses the tag strip against the feed roller 124, this being effected by a com-pression spring 138 positioned on the top 23 within an inverted cup 139 provided on an arm-like extension 140 of a collar 141 which is secured to the shaft 133, as illustrated in FIGURE 22.

It will be apparent from the foregoing that when the yoke 132 is lowered by the spring 138 and the feed roller 124 is rotated by the crank 127 in the direction of the arrow 142 in FIGURE 20, the tag strip 13a will be fed or advanced along its path between the guide rails 67 toward the primary station 18. The extent of this feeding movement is such as to advance the tag strip by a distance corresponding to the dimension of one tag 13, that is, the distance between adjacent markings 66 on the tag strip 13a. On the other hand, when the rol-ler 124 is turned by the crank 127 in a direction opposite to the arrow 142 and the yoke 132 is raised by the solenoid 137, no feeding movement will be imparted to the tag strip.

'Ihe solenoid 137 is -in circuit with a suitable source v of current and remains energized until the current supply is interrupted by a switch 143 which is secured to the frame 22 and is actuated by a follower roller 143a engaging a cam track 144 on the periphery of the cam 32. Upon de-energization of the solenoid 137 by Vthe switch 143, the spring 133 automatically lowers the yoke 132'.

The intermittent feeding of the tag strip 13a is coordinated with the `separation of the yfree edges at one side of the bag 10 on the station 18 by the suction heads 71, 72, so that when these edges are separated, the tag strip is ladvanced by a distance equivalent to one tag, whereby the leading vtag in the strip is inserted into the bag, with ran edge of the leading .tag disposed between the Kseparated bag edges. The'suction head 72 is then brought down so that the knife blade -97 severs the leading tag from its strip, and the partly completed bag is now ready for further processing.

For this purpose the bag together with the insented tag are shifted or delivered from the primary `station 18 to the secondary station 20 which has the sewing machines 21 located at its opposite sides, so .as to secure together the `free edges `at both sides of the bag by the lines of stitching `16 and simultaneously 'secure the tag 13 between the free edges at the -side of `the lbag where it has been inserted.

The means for delivering the bag and the inserted tag from the station =18 to the station 20` involve the provision of an elongated guide 145 which is secured at one end thereof to `a collar l146 on `a stub-shaft 147 journal-led in bearings `1418 on .the frame 22. The other end of the guide 145 has secured ythereto a rigid arm 149 which, in turn, is pivoted at 150 to an actuating rod 151 passing ldownwardly through the top 23. The lower end of the rod 151 is pivoted to a cam lever l152 on the aforementioned shaft 61, the lever 152 having a `suitable follower 153 (see FIGURE 16) engaging .a cam track in a cam, namely, the cam 130, on the shaft 31. By vir-tue of this arrangement, the guide 145 may be raised and lowered relative to the top 23, as will be apparent. A carrier 154 is reciprocable on the 4guide 145 by means of an actuating rod 155 which extends between the carrer and an oscillatory crank 156 the latter being movable in a horizontal plane and affixed to the upper end of a shaft 157 journall'ed vertically in suitable bearing means 158 provided on the frame 22. The lower end of the shaft 157 carries a Icrank 159 which,` as shown in FIGURE 16, is lconnected to a cam lever 166 having a follower 161 engaging a suitable groove or track in the )aforementioned cam 63.

As is best shown in FIGURES and 1l, the carrier 154 is provided at fthe underside thereof with a bearing block 162 in which is rigidly secured a cross-shaft 163 having a pair of arms 164 rigidly secured thereto, whereby the arms `164 are rigid and stationary relative to the carrier. The free ends of the arms 164 have pivot-ally connected -thereto at 165 la pair of presser feet 166, one for each arm, and leaf springs \167 are provided on the arms to engage the presser feet and maintain the same substantially parallel with the top 23 when the guide 145 is lowered as shown in FIGURES 11 and l2. With the guide 145 lowered and the carrier 154 at the end of the guide adjacent the shaft 147,l sliding of the carrier in the direction of the arrow 168 in FIGURE 1l will cause the presser feet 166 to slide the bag and the inserted tag from the primary station 18 to the secondary station 20 for operative engagement of the side edges of the bag by the sewing machines 21. Then, when the carrier 154 reaches the end of its travel `at the station 20, the guide 145 is raised, thus raising the carrier `and the presser feet 166 therewith and permitting return of the carrier to its initial position with the feet 166 in their raised position, in readiness for subsequent lowering and engagement with the next bag.

Apart from the presser feet 166 which deliver the bag from the primary to the secondary station, the bag is also engaged during this travelV by an arcuate finger i169 which .is -secured at one end thereof to a shaft 170 pivotally mounted in a bearing 171 at the underside of the carrier '4. The linger 169 extends over and beyond .the shaft 163 and is provided .at its free end with a pivotally mounted finger piece 172 with twin prongs 17211 which are adapted to engage the bag at a poi-nt overlying the tag `13 inserted therein. The i'inger piece `172 engages the bag while the carrier '154 is'in its initial position -as shown in l FIGURE 1l. However, when the Ysuction head 72 is raised to separate the edges of the bag for insertion of the tag therebetween, la detent inthe -form of a screw 173, provided on the bar 87 engages the underside of a roller 174 mounted o-n a stub shaft 175 on the nger 16,9, whereby the 4finger and the associated -il'inger piece 172 are raised out of engagement with the bag to permit insention of the tag therein, as shown in FIGURE l2. With the lowering of the suction head 72, the linger piece 172 is again brought in contact with the bag at a point overlying the inserted bag and so remains during the travel olf the carrier 154 to the secondary station 26. When the carrier 154 is in the position shown in FIGURE 10, that is, remote from the suction head 72, and the guide 145 is raised as shown, the finger y169' simply drops downwardly somewhat, to the extent-permitted by engagement of the stub shaft 175 with the top edge of the adjacent of the arms 164.

Suit-able guide members or rails 176, 177 Iare provided on the top 23 at opposite sides of the bag travelling from the primary to the secondary station, such members or rails being equipped with slotted mounting bases 178 to achieve mounting screws 179, whereby the positioning of the guides on the top 23 may .be adjusted. Also, a wire spring 1811 is aflixed to one of the screws 179 and extends into the path of the bag travelling to the station to prevent possibile creasing or other displacement of the b'ag in that region.

The bagwith the inserted .tag is conveyed past the sewing machines 21 by pairs of feed rollers 181 mounted, as is best shown in FIGURE 7, on parallel shafts 182 suitably journalled in the machine and connected for simultaneous rotation by suitable gearing v183. One of the shafts 182 is driven by an endless belt or gearing (not rails 67 and is secured to the top 23.

normally pressed downwardly against the tag strip by a l 10 shown) to the source of power which drives the atformentioned pulley 34.

A gravity actuated arrn 1184 is pivotally mounted on the upper of the shafts 182 and carries a roller 185 which urges the bags travelling to the secondary station 20 so that they lie flat on the top 23, the roller 185 cooperating with a similar roller 186 mounted on a shaft 187 under the top 23, Ias shown in FIGURE 7. After passing through the rollers 1185, 187 and pairs of rollers 181, the bags are delivered to the Stringing machine, as indicated in FIG- URE 3. o

A rigid `guide .plate 188 is secured to the suction head 72 above .the station 18 so as .to `guide the leading edge of the web lita under the suction head. Similarly, a wire guide 189 is provided transversely of the guide rails 67 adjacent the roller 65 (FIGURES 3 .and 20) in'slightly spaced relation above the top 23, to `guide the tag strip 13a between the rails 67. Moreover, the tag strip 13a is tensioned during its travel between the rails 67 toward the station 18 by means of a leaf spring 190 which, as shown in FIGURE 20, is secured to the underside of a bracket 191 which bridges the path of the tag strip between the The spring 190 is lever 192 pivoted to the bracket 191, but this lever may be released to permit upward bending of .thespring and thereby yfacilitate feeding of the tag strip to the primary station by hand, when necessary, such as for example, when the machine is initially set in operation or aliter the passage of the tag strip to the primary station is for some reason interrupted. With further reference to FIGURE 16, lit may be noted that suit-able spacer sleeves 193 are provided on the shafts 61, 93 lto separate the respective cam" levers 59, 152 and 91, 120, 128 Ithereonand that suit-able Abrackets 194 are provided on the frame 22 for the camshaft-31.

Although the opera-tion of the invention will be understood from the foregoing disclosure,`it may be suinmarized as follows: Y

Operation The web 1a`unwound from the roll 10b and khemmed at its longitudinal edges as shown at 12 is doubled longitudinally upon itself as indicated at 10c and is fed by the rollers 17 intermittently to the primary station 18 while the guide 37 is raised and the knife carrier 36 Vtravels tothe position 36a shown in FIGURE 5. When feeding of the web is interrupted by the clutch 26, the guide 37 is lowered and the cutter or knife 35 severs an individual brag 10 from the web during movement of the carrier 36 in the direction of the arrow 43.

The severed bag remains temporarily stationary on the primary station 18 and, with the guide 145 and carrier 154 in the position shown in FIGURE 1l, the suction heads 71, 72 are energized by the valve 114 and as the upper suction head 72 is raised to separate the edges of the bag for insertion of the tag,the finger piece 172e is raised simultaneously 'by engagement of the roller 174 with the screw 173 to facilitate such an insertion, as illustrated in FIGURE l2. In this regard it may be noted that although the head 72 is raised, the guide 145 remains lowered and -t-he presser feet 166 remain in engagement with the bag, thus clamping the bag against the table top 23..

The tag strip V13a is then advanced toward the station 18 by the feed roller 124 so that the leading tag inthe strip is inserted in the bag with an edge thereof disposed between the separated edges of the bag. When the leading tag is inserted to the appropriate extent, the photoelectriclcell 69, responding to the markings 66 on the tag strip, energizes the solenoid 137 so as to raise the roller 131 and interrupt the feeding movement of the tag strip. The tag strip then remains stationary until the roller 131 is again llowered by interruption of ow of current to the solenoid through the switch 143 for the subsequent cycle of operation. After insertion of the tag into the tag, the rocker Karm 99 is moved by the rod or link 104 so that the clamp member 101 moves downwardly and away from the top or mouth of the bag, the latter being held clamped against the top 23 by the presser feet 166. When the member 101 comes in contact with the bag lying on the top 23, downward movement of the member 101 is arrested and continued actuation of the rocker `arm 99 causes the spring 103 to apply pressure on the clamp member 101 so that it moves away from the top or mouth of the bag and pulls the upper wall of the bag away from the suction head 72 so that it lies tightly upon the bottom wail of the bag and the edge portion of the tag inserted between the bag walls. By having the bag stretched tightly between the presser feet 166 and the clamp member 101, the two lead-ing corners of the tag do not catch or hang on the bag walls while the tag slides to the limit of its insertion into the bag.

The lowering of the suction head 72 causes the knife 97 to sever the leading tag from the tag strip 13a and after this severing ope-ration is completed, the head 72 returns to its initial, raised position. By that time, the presser feet 166 which `are already in engagement with the bag and the finger piece 172 which has been brought into contact with the bag by the lowering'of the head 72 coact with the sliding movement of the carrier 154 on :the guide 145 in the direction of the arrow 168 and thereby deliver the bag Iand the inserted tag to the secondary station 20, where the sewing machines 21 stitch the side edges of the bag and the tag therebetween.

Upon delivery of the bag to the secondary station, the guide 145 with the carrier 154 is raised, thus disengaging the feet 166 as well `as the nger piece 172 from the bag and facilitating return of the carrier to its initial position for the next cycle of operation.Y Inthe meantime, the rollers 181 cause the bag to travel past the sewing machines 21 for delivery to the Stringing machine.

It may be noted that the screw 173 is adjustable as to height in the bar 37 with respect to proper setting for engagement with the roller 174 `and may be locked in a pre-adjusted position by a setscrew 195.

Although the machine is primarily intended for the manufacture of bags of cotton or llike fabric material, having stitched hems 12 and lines of stitching 16 at the sides thereof, it may be also used for production of bags of plastic, or the like, wherein heat sealing is sub stituted for the stitching operations.

Thus, while in the foregoing there has been described and shown the preferred embodiment of the invention, various mo-dicatio-ns may become apparent to those skilled in the yart to which the invention relates.
